JOHN HANLON, OF NEW YORK, N. Y., ASSIGNOR TO WILLIAM W. GIBBS,

OF SAME PLACE.

GAS APPA RATUS.

SPECIFICATION forming part of Letters Patent No. 254,213, dated February 28, 1882. Application filed July 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN HANLON, of the city and State of New York, have invented certain new and useful Improvements in Gas Apparatus, of which the following is a clear, full, and exact description, reference being bad to the accompanying drawings, making part of this specification, in which- Figure l is an elevation, partially in section, of a condenser. Fig. 2 is a cross-section through the same. Fig. 3 is a cross-section of apurifier. Fig. 4 is a detached perspective view of the'liquid seals for the cut oft, with suitable elastic packing.

The object of my present invention is the condensing and purifying of illuminating-gas;

and it consists in the several combinations of devices hereinafter explained and claimed.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In thesaid drawings, the condenserF is com-,

same. I provide each condensing-cylinder at its top with a combined elastic and water packing to insure a tight joint, which is essential. To this end I construct around the head of each cylinder a cup, in the bottom of which is snugly fitted an elastic annulus of suitable material, and the cup is then partiallyfilled with a liquid to receive the dip-rim of the cylindercap. This forms a compound seal, which secures the gas against the possibility of escape through the top of the cylinder. Each cylinder is provided with a central Vertical diaphragm, which causes the gas to pass up one side of each cylinder to the top, and'again down on the other side of the diaphragm, and so on through the whole condenser. The lower portions of the cylinders rest in a liquid seal of any ordinary construction.

The purifier is of the usual construction,

with two compartments supplied with the customary purifying materials. Below this purifierI placethe longitudinal central crankturn of the shaft J. The liquid seals 2' are loosely journaled in bearings formed on the cross-arms K, and by this construction the liquid is allowed to retain at all times a level sealing-surface. In the bottom of the sealingcups 1', and below the liquid, 1 place a thin sheet of suitable elastic packing to guard against the evaporation of the water seal, thus forming in each cup a compound seal.

I am aware that awater sealin gas-purifiers is not broadly new, nor do i claim such as my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. The condenser F, composed of a series of vertical cylinders, surrounded with water jackets and provided withdiaphragms, in combination with a cold-water pipe connecting directly with each jacket and a discharge-pipe similarly connected, substantially as and for the purpose described.

2. The cylinders f, havingtlie cups g, provided with a rubber packing and water seal, in combination withthecylinder-cap provided with a dip-rim, substantially as and for the purpose described.

3. The purifier I, ,in combination with the central crank-shalt, J, and tliesealsi, connected therewith, whereby the compartments are cut off or opened, substantially as described.

4. The central shaft, J, provided with the V JOHN HANLON.
